Which of the following statements is correct? Assume that the project being considered has normal cash flows, with one outflow followed by a series of inflows. O If Project A has a higher internal rate of return (IRR) than Project B, then Project A must have the lower net present value (NPV) O If Project A has a higher IRR than Project B, then Project A must also have a higher NPV O The IRR calculation implicitly assumes that all cash flows are reinvested at the weighted average cost of capital (WACC) O The IRR calculation implicitly assumes that cash flows are withdrawn from the business rather than being reinvested in the business O If a project has normal cash flows and its IRR exceeds its WACC, then the project's NPV must be positive
